How should I store my LifeStraw Peak Series Personal Water Filter Straw?

Avoid drying out the filter by storing with a saline solution made by mixing a teaspoon of salt with water . This will keep the filter at its highest performance and maintain the hydrophilic properties of the membrane, while also preventing any mold or algae from growing during long-term storage. When the membrane becomes completely dried out, it can be difficult to get water to flow through again.

REGULAR CLEANING AND STORAGE

Mix 1/4 teaspoon household bleach solution with 1-2 cups of water. Dip the filter into the bleach solution far enough so that the end is submerged in solution, and use the backwash accessory (or blow into your filter if using your Peak Series personal water filter straw) to push and pull the solution from the filter several times. Rinse with tap water. For your squeeze bottles and gravity systems, we recommend cleaning all mouthpieces, caps, and parts for optimal disinfection.Follow these steps if you have already used the LifeStraw Peak Series filter and you plan to store for greater than 1 month without use. If storing for longer than 3 months, we recommend cleaning with a diluted bleach solution prior to storage for increased disinfection. 

LONG TERM STORAGE

1. Immerse in Salt Solution. Fill a reusable container with 2 cups of water, add 1 teaspoon of salt and dissolve. With the bottom cap open, take a few small sips of salt water until the solution reaches the top mouthpiece. Close the caps to prepare for storage and to hold the saline solution inside.

2. Store. Place the water filter straw into a reusable container and store in a cool, dry place.

3. Resume Use. To use your water filter straw again, blow any remaining solution out of the filter. We recommend spitting out the first few sips of water as they may still taste salty.
